I lost the key to my 2004 cadillac CTS last night. I should be receiving the spare key in the mail tomorrow from my parents. HOWEVER, I had to take my car into the shop a few weeks ago. The computer system either needed to be repaired or replaced, I can't remember. Will my spare key start the car, or does this key need to be reprogrammed? I either need to find a ride to work ASAP or count on this key to get me there, if I can't make it I may lose my job.

I have the same car and I had my computer system repaired once and my spare key I got with the car still started it fine when I lost my keys for a few days. I would get a backup ride just incase though, I suppose its not always the same
